What is the best glide ratio for a 747?


What is the best glide ratio for a 747? A fully loaded 747 has a glide ratio of 15:1 meaning that it travels 15 feet horizontal for every foot of vertical drop. That means at 35,000 feet it could travel about 100 miles. The new 787 Dreamliner is around 20:1.


How far can a 747 glide from 30000 feet?

The lift-drag ratio for commercial airliners is about 16:1. The distance that a 747 could glide is a function of altitude. Gliding from cruise altitude of 30,000 ft, or about five miles would have a range of 80 miles.


What is the glide ratio of a Boeing 777?

With it's efficient wings the glide ratio of the B 777 should be around 15:1. Extrapolating, from a Flight Level of 390 gives us a theoretical gliding distance of about 110 Miles.


What is the maximum glide slope for a 737?

Maximum and minimum glideslope angles are 3.25 degrees and 2.5 degrees respectively.


What is the climb speed of a 747?

During normal flights, the 747-400 & 747-8 has a climb rate ranging from 2000 to 4000 feet per minute.


What is the best glide speed for a 747 400?

Just found on a techie forum that in a 747 in clean configuration (ie flaps and gear up) you should aim for V2+80kts as your best glide speed.


What is the glide ratio of a A380?

The A380 has a glide ratio of about 15:1, which means that for every 15 kilometers (9 miles) it travels horizontally, it loses 1 kilometer (0.6 miles) of altitude. Therefore, if an A380 is cruising at 12 kilometers (7 miles) above sea level, it can glide for about 180 kilometers (110 miles) before reaching the ground.


What is the longest glide on a 747?

Without engine thrust, a 747-200 has a glide ratio of roughly 15:1, meaning it can glide forward 15 kilometres for every kilometre it drops. The flight crew quickly determined that the aircraft was capable of gliding for 23 minutes and covering 91 nautical miles (169 km) from its flight level of 37,000 feet (11,000 m).


What is the glide ratio of a Boeing 727?

Different aircraft have different glide ratios. A Boeing 747- 200 had a glide ratio of 15:1, and a Boeing 727 has a ratio of 17:1.
